Vintage Seiko 6206-8990 Weekdater

The price is $500 I acquired this watch as part of a group lot. I'm selling it because it does not match my collection or interests. I was told it was serviced, but I do not have any records or history of this piece. So far, it has been keeping good time. I do not have a timegrapher, so I can not verify the beat because it is a vintage piece, it is being sold as is and may need to be serviced. Pickup only, I'm at Hurontario and Bovaird in Brampton. Fast pickup, no holds NO TRADES
